additional information | substrate specificity and enantioselectivity, overview, the enzyme catalyzes the Baeyer-Villiger oxidations of prochiral 4-substituted ketones, e.g. 4,4-disubstituted cyclohexanones, to the corresponding lactones, configuration of lactone products, 4-tert-butylcyclohexanone is a poor substrate for wild-type and mutant enzymes, no activity with 4-hydroxy-4-phenylcyclohexanone of wild-type enzyme and mutant F432S, 4-tert-butylcyclohexanone is a poor substrate | Escherichia coli | ? | - |
